Hazards and Protection.
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Do not store in metal containers.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation. Wash clothing before reuse.
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Vacuum or sweep up material and place into a suitable disposal container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Remove all sources of ignition. Provide ventilation.
Stable at room temperature in closed containers under normal storage and handling conditions.
Acid anhydrides, acid chlorides, strong oxidizing agents.
Hydrogen chloride, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. May polymerize explosively when involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Combustible material; may burn but does not ignite readily. Extinguishing media: Use agent most appropriate to extinguish fire. Do NOT get water inside containers. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. Cool containers with flooding quantities of water until well after fire is out.
This material is probably combustible.
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
Fire may produce irritating, corrosive and/or toxic gases.
Effects may be delayed.
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. 1. Burning pain in mouth and throat. White necrotic lesions in mouth, esophagus and stomach. Abdominal pain, vomiting ... and bloody diarrhea. 2. Pallor, sweating, weakness, headache, dizziness, tinnitus. 3. Shock: Weak irregular pulse, hypotension, shallow respirations, cyanosis, pallor, and a profound fall in body temperature. 4. Possibly fleeting excitement and confusion, followed by unconsciousness. ... 5. Stentorous breathing, mucous rales, rhonchi, frothing at nose and mouth and other signs of pulmonary edema are sometimes seen. Characteristic odor of phenol on the breath. 6. Scanty, dark-colored ... urine ... moderately severe renal insufficiency may appear. 7. Methemoglobinemia, Heinz body hemolytic anemia and hyperbilirubinemia have been reported. ... 8. Death from respiratory, circulatory or cardiac failure. 9. If spilled on skin, pain is followed promptly by numbness.
Causes respiratory tract irritation. Can produce delayed pulmonary edema.
Causes skin irritation.
Causes eye irritation. May cause chemical conjunctivitis.
Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
